THE HIGHLIGHT OF RATTLESNAKE CANYONis a polished slot canyon located 0.4 miles up the wash from the picnic area. After rainstorms, water swirls in large potholes as it cascades down through the multi-leveled canyon. Some of these potholes retain wather throughout much of the year.

For many hikers, the slot canyon and adjacent smooth slab are a natural barrier to further travel. Head east from the picnic area to a large wash, then go south up the wash. The was soon become cluttered with boulders. To reach the base of the slot canyon, some moderate boulder scrambling is necessary.
